/**
 * Base Flutter synthetic action.
 *
 * <p>A synthetic action is not a real gesture event issued to the Android system, rather it's an
 * action that's performed via Flutter engine. It's supposed to be used for complex interactions or
 * those that are brittle if performed through Android system. Most of the actions should be
 * associated with a {@link WidgetMatcher}, but some may not, e.g. an action that checks the
 * rendering status of the entire {@link io.flutter.view.FlutterView}.
